I answered a question recently and it seems like upvotes don't contribute to my reputation.
I've edited the answer like 14 times so is it possible that my answer turned into a "community" answer and upvotes don't contribute to my reputation?
Yes, after a certain number of edits by you and/or others the answer becomes community wiki and further upvotes don't contribute to your reputation points. This limit is in place to prevent gaming the system by bumping a question to the main page to get it some attention and consequently upvotes.
